Inspect every 10,000 km, replace every 20,000 - 30,000 km.

Spark Plugs:

Replace every 40,000 - 60,000 km (depending on plug type, e.g., iridium).

Timing Belt Chain:

The JB-DET engine uses a timing chain, which is generally maintenance-free and designed to last the life of the engine. However, inspections are recommended.

Engine Oil:

API SN or higher, viscosity 0W-20 or 5W-30 (refer to owner's manual for precise specification).
